Patented Oct. 11, 1938 UNITED STATES PATENT OFFIE 7 Claims,

This invention consists in improvements in the type of narrow-ware loom set forth in the Emery patent, No. 1,057,133, in which the shuttles are arranged in superposed rows or banks in an b auxiliary batten structure, together with their respective racks and pinions for moving the shuttles; such batten structure is movable up or down to bring some particular shuttle-bank to the same elevation as a row or bank of warp =sheds; each rack has at one end means, as a picker-plate, by which, when. such particular shuttle-bank and hence the rack therefor are at said elevation, movement of the rack and hence said shuttle-bank is effected; slides, reciprocating-together toward and from each other, are present having pickers to engage said means and effect such movement but being normally held in retractive position; and there are respective means related to the two slides for moving their pickers to active position when the slides move apart. In such looms, because there is only one pair of pickers, only one bank of fabrics can be woven at a time, the several banks of shuttles all serving the single bank of warp .sheds (asthose of one bank supplying ground weft and those of the other banks figure weft, as of different colrs),but one at a time.

According to the present invention the loom as improved thereby can be made to operate the same as the said Emery loom, i. e., to weave only one bank of fabrics at a time, or it can be made to operate so as to weave two or even three fabric banks at a time. When it is weaving one fabric bank any number of the shuttle- .1 banks may partake in the Weaving, of course only one shuttle-bank at a time entering the bank of Warp sheds. When it is weaving two fabrics at a time all the shuttle-banks partakein the weaving but the four shuttle-banks are active as 4o pairs; that is, those of one pair are made respectively to pass through the two sheds and then those of the other pair, and so on, alternately. When it is weaving three fabrics at a time three shuttle-banks partake in the weaving, all passing through the three banks of warp sheds simultaneously. These possibilities exist through the use of three pickers to a slide and novel means whereby one or more of such pickers are brought into action when the corresponding I slide approaches the end of its outward stroke.

In the drawings,

Fig. 1 is a front elevation, partly broken away, of one end portion of the improved loom;

Figs. 2, 3 and 4 are fragmentry elevations of the auxiliary batten structure, Figs. 2 and 3 showing two different arrangements of the warp sheds for the weaving of two fabrics at once, and Fig. 3 showing an arrangement of the warp sheds when three fabrics are woven at once, the warp sheds in all cases appearing open;

Fig. 5 is a section on line 5-5, Fig. 1;

Fig. 6 is a fragmentary plan, partly in section, of parts at the extreme right-hand end of the loom in Fig. '1, including the means by which the pickers undergo selection; and

Fig. 7 is an elevation, as seen from the left in Fig. 6, of the unit whereby the selection of the pickers is eifected, and Fig. 8 a side elevation of right-hand spindle 3|.

The following parts of the 100m are or may be all substantially the same as in the said Emery loom: The loom-frame l the main batten 2 supported by lay-swords 3; the auxiliary batten structure including superposed horizontal rails 4a and spaced blocks ib Whose races 40 receive the shuttle-banks, here four in number and designated 5a5b-5c5d; the reciprocating racks 6 for driving the shuttles through intermediary pinions l in the blocks; the means 8, movable in the main batten and actuated from suitable pattern mechanism, for moving the auxiliary batten vertically; the upstanding brackets 9 aflixed to said main batten and connected by the guide-rods In; the picker slides ll movable on the guide-rods; and the means for moving the slides together from and together toward each other comprising levers l2 fulcrumed on the main batten and linked to the slides at l3 and to each other at l4 and one of which is connected by a link [5 with a crank it one shaft I! journaled in a bracket 58 depending from themain batten and such shaft being constantly rotated through gearing it from a shaft 20 journaled in the frame. So, also, are or may be the plates 2| on the ends of the respective racks and having forward projections 22 sliding on guide-rods 23 carried by brackets 24 on the auxiliary batten structure, said projections carrying superposed picker-plates 25.

Now according .to my invention there are'three pickers 26a-26b-26c pivoted to each slide, in superposed relation and spaced (that is, from center to center) the same as are the picker plates. And these pickers are normally held retracted (Fig. 6) by springs 26m and subject to means by which each may be brought to active position, to wit, so as to engage in its notched inner end, as in the Emery patent, the picker.

plate which happens to be alined therewith and thus move the corresponding rack and shuttlebank on movement of the slides toward each other. Thus:

A projection 21 on each bracket 9 has tapped into it a sleeve 28 in which is a plunger 29 having a head 2911 at its outer end and normally held with said head bearing against the sleeve by a spring 30. The inner end of the plunger has a head 2% and this has a terminal stop a which projects into the path of the outer end of the picker 26a alined therewith when the latter moves toward the same. All these parts are in effect parts of the main batten structure. Rotatively adjustable in the portion 28b is a vertical spindle 3| and this has other stops arranged as follows: A pair of lateral stops 1) and c projecting at right angles to each other and arranged in the same horizontal planes as the picker 26b, and a pair of lateral stops (5 and e projecting oppositely to each other and ar-'. ranged in the same vertical plane as the stop and in the same horizontal plane as the picker 260. There is means, as a screw 32, for securing the spindle in any position to which it is adjusted.

When the loom is to be operated as in the Emery patent, or for the weaving of a single bank of fabrics, the spindle is so positioned that the stops b c and a3e are inactive or out of the paths of the pickers 2611-260 as they move out ward with the slides; that is, the spindle is turned so that stops de are in a line perpendicular to the axis of stop a and stop b projects oppositely to stop a. Then only picker 25a can be moved to active position, to wit, by stop a.

Suppose the weaving is to proceed with respect to two banks of warp sheds simultaneously, as A-A in Fig. 2 or BB in Fig. 3. In the first of such cases the spindle is positioned as in Figs. 1 and 6, or with stop b projecting in the same direction as stop a, or so that pickers 26a and 2517 will be actuated by said stops on the outward movement of the pickers with the slide; then, according as the pair a5b' or the pair 5c-5d of shuttle-banks has been brought into alinement with the sheds AA so that pair will be made to partake in the weaving. In the second case the spindle is positioned as in Figs. 7 and 8, or with stop d projecting in the same direction as stop a,

or so that pickers 26a and 250 will be actuated by.

such stops; then, according as the pair 5a-5c or the pair 5b5d of shuttle-banks has been brought into alinement with the sheds BB so that pair will partake in the weaving.

If it is desired to weave three fabric-banks at once, as with the use of three warp sheds C, then the spindle is so positioned that the stops 0 and e project the same as stop a, resulting in the call of pickers 26a 25b26c by the three stops a.ce on the outward stroke of the slide and the movement of the shuttle-banks 5a--5b5c.

Thus by equipping the loom with the means shown at the right in Fig. 6 and in Figs. 7 and 8 the loom is adapted to the weaving of one, two or three fabric-banks at a time.

Having thus fully described my invention what I claim is:
